How the connector works

The connector authenticates using IAM role assumption (sts:AssumeRole with an external ID supplied by Horizon Catalog) and then:

  1. Auto-discovers the cluster or workgroup endpoint.
  2. Auto-detects the audit log destination (S3 or CloudWatch for provisioned; CloudWatch only for serverless).
  3. Reads query logs to build popularity and lineage data.
  4. Queries Redshift system views for schema and table metadata.
